I’ve found these 9L-6969 fuel injectors to be a total lifesaver for anyone running Caterpillar 3208 or 3204 engines in their heavy equipment. Whether you’re restoring a D3 loader or keeping a 225 excavator in the field, this four-piece set delivers the precise spray pattern needed to get your engine idling smoothly again. It is a fantastic find for mechanics who need reliable, direct-fit replacements without the steep markup of OEM parts.
